Kid on the D train with a dodecahedron puzzle cube. (Think a rubik's cube with 12 faces and 11 facets on each face.)

I'm watching him mess with it thinking he's just playing, but then I realize he's doing a solving algorithm.

That kid's going to show up after break speed-solving a megaminx and […]

I've been working on a small DSL embedded in Python to compute exact (to machine precision) probabilities for small simulations. A good example is the D&D dinosaur fight whose probabilities I computed with Mathematica a few weeks ago. Now you can write your […]

I would just like to say that Katie Hoody's NYTimes crossword puzzle today has an absolutely beautiful grid. Nice puzzle too! But just look at that in black and white.

The diffusers on the new LED polyhedron (dihedral hexacontahedron, right) looked so much better than the first build that I had to print new ones for the truncated icosahedron (left). I also synced up the patterns on both builds (with #pixelblaze) and will be […]

When I tell people I like to fold cones and cylinders, they imagine I am folding a flat piece of paper and later gluing it into shape. And not without reason. Only a madman would make curved creases on a preformed cone.

But since this is a […]

The specific page that prompted me to post about this book is the description of how the first stellation of the rhombic dodecahedron can be dissected into six congruent pieces (and, in passing, that it can also fill space)

Most of this book was written before I was born (and I'm hardly a spring chicken) but I've only just got it & I am enjoying it inordinately.

I can't even think about the real question here, because my brain has been short-circuited by the ‘fundamental result of Lucas’ quoted in the preamble.

How cool is that‽
